February 09, 2021. Editors' Choice: Mn-Doped CeO 2 Catalyst for Hydrogen Production. Hydrogen for the use in fuel cells can be produced by ethanol steam reforming (ESR) with H 2 and CO 2 as main products and CO and CH 4 as by-products. Ethanol is a suitable hydrogen source due to its non-toxicity, low production cost, production capability from biomass, and hydrogen-richness.
